HORIZONTAL-CARD SYSTEM.

Application filed August 3, 1925, Serial No. 47,924, aid in Austria and Germany August 3, 1925.

The invention relates to horizontal card index systems of the overlapping card type, in which a series of card holders or card supports are,removably mounted in a frame or drawer and a series of cards are removably held by the card holders in such a manner that they may be removed from their respective cardholders or supports I without removing the latter from the frame.

One object of the invention is to provide improved means for mounting the card holders or supports in the frame or drawer. Anotherv object of the invention is to provide'improved means for detachably securing the cards to the card holders or supports. A still further objectof the invention is to provide improved protectors for the lower margins of the cards.

NVith these and other objects inview, the invention consists in certain novel features as hereinafter set forth and pointed out in the claims. In the accompanying drawings: ,7

Fig. 1 is an end view showing two interengaging spacer blocks serving for receiving the rotatable card holders or supports.

Fig. 2 is a part plan showing two adjacent spacer blocks and parts of the. card supports mounted therein, also one part of the card attached to one of the card supports.

Fig. 3 is a plan showing the lower margin of the card and the protector attached -thereto.

Fig. 4 is a detail view of the lower corner ofa'cardy Fig. 5 is a perspective view of a spacer block and the adjacent portion of a card support rotatablymounted therein. a

Fig. 6 is a perspective View partly broken away showing a unit consisting of two.

spacer blocks, a card support and a card at- Fig. 7 is a detail view of or protector, and

' Fig. 8; 1s a perspective view showing a frame or drawer containing a number of part of a sheath Fig. 9. is a transverse section through the frame shown in Fig. 8. I

Each card a (Figs. 2 and 6). is detachably secured to a rod 0 which at both ends is rotatably mounted in'bores f of blocks 6. Two adjacent blocks 6, e have interengaging surfaces for which purpose one end surface of each block is made convex, whilst the concave,

are held therein by a slidable bridge member mwhich may be locked in position in the usual manner. The blocks 6 serve not only as bearings for the card supports 0 but serve also as means for spacing the card supports "0 and for ensuring proper over- 6 lapping of the cards a. V For detachably securingthe cards a to the rods 0 the latter are formed or provided with two forks (i, d (Fig. 6) each fork having two prongs (Z, d extending parallel to the rods 0 and a stem extending at right angles to the rod 0.. The card a is provided with lateral notches in by means of which it. may by slipped over the inner prongs. As may be seen particularly from Figs. 2 and 6 the stem of the fork and the outer prong d lies on one side of the card whilst the other or. inner prong lies on the ether side of the card. -The card is therefore very firmly held by the prongs and is stiffened by the prongs, the means for securing the card to the rod a lying practically in the plane of the card. It will also be noticed that the means for securing thecard'to the rod are extremely light.

The lower margins of the cards are protected both at the front and at the back by means ofprotectors made, for instance of celluloid. These protectors serve as usual for protecting the margin and also for the insertion of supplemental cards and signals. Each protector is made from a single strip of'celluloid by doubling same in such a manner as to form two parallel members and 7c of different widths (Fig. 7). The wider member is is formed near the ends with av vertical incision and the flaps 9 thus obtained are folded inwards so as tg lie between the member 70 and the membercj. If desired the fiaps 9 may be glued to the member y. A socket is, in this manner, produced between the flap 9 and the adjacent portion of the member 7a. Into these sockets are introduced the portion aof the cards, which are divided from the body of the card a by cuts '11 as-shown in Fig. 4:. The portions or tongues a engage the tongues and extend preferably right down to the bottom of the protector.

It will be seen that by this construction of the interengaging partsof the card and the protector, very easy insertion and removal of the card into and from the protector or sheath may be effected and that there are no projecting parts projecting outside from the surface of the card or the protector, the socket and tongue lying between the two members j and Id of the protector; The manufacture of the protector and card is also very easy and cheap, and practically the whole length of the protector may be utilized for the insertion of a supplemental card or signals, the means of connection being at the extreme ends of the card.

' porting The protector may, as usual he made of transparent material and the various protectors may be made of different colours and used as signals.

I claim: g ,c

I. In a card index system, a frame, two series of interengaging spacer-blocks, removably mounted in said frame, said blocks having bores and two adjacent blocks having corresponding convex and concave adjacent end faces, and a series of card-supporting members each rotatablygmounted in the bores of two said spacer blocks, sub stantially as described.

2. In a card index system, a frame, a series of card-supporting members removably mounted in said frame, a series of cards detachably secured to said card-supmembers, each eard-su porting member being rovided with two orks for clamping a cart, said forkscomprising two prongs and a stem, and said cards having cut-out lateral notches to enable the cards to be slipped between the prongs and held by one of them on each fork against removal from the rod, substantially as described.

In a card index system; a frame; a series of card-supporting members removably mounted in said frame; a series of cards detachably secured tosaid card-supporting members; each card-supporting member comprising a rod, two transverse stems projecting from the rod and two prongs projecting from each of the transverse stems in adirection parallel to the rod; and each card having lateral notches to enable such card to be slipped between the prongs and held by one of them on each fork against removal from the rod, substantially as described.

4. In a card index system; a frame; a series of card-supportin members removably mounted in said frame; a series of cards secured to said card-supporting members; and a series of protectors for said cards, each protector having two parallel members and sockets formed at the ends of one of the parallel "aembers by inwardly and downwardly turned flaps, each card having at its corresponding ends lateral tongues engaging said sockets, substantially as described.

5. In a card index system, a frame, a series of car-supporting members removably mounted in said frame, a series of .cards secured to said card-supportin members; and a series of protectors for t e said cards, the said protectors each comprising two parallel members of different widths, the member of greater width being formed cat the ends with transversely turned-in flaps to form sockets, and each card being formed with incisions to form oppositely extendin tongues adapted to engage said sockets an hold the protector.

6. In a card index system, a frame, two series of interengaging spacer-blocks removably mounted in-said frame, a series of cardsupportin rods, each rod being rotatably mounted in two said spacer-blocks and provided with two forks extending towards each other from stems arranged at right angles to the rods, a series of cards adapted to be held upon the prongs of said forks and a series of protectors for the said cards, said protectors comprising each two parallel members, one of said members having at the ends turned-in flaps to form sockets, and the cards having incisions at the side edges to provide oppositely extending tongues adapted to enter said sockets.

In testimony whereof, I'have signed my name to this specification at Prague, Czechoslovakia, this 20th July, 1925.
